Originally posted by reeftool Much of this discussion will likely depend on one's financial position. For the guy that has to save for months to buy a lens, having his system abandoned can be catastrophic. For someone else, maybe just an annoyance.
"Catastrophic" is a rather dramatic term.
I bought my Q-7 at a time when our cash flow was weak because of what could truly be called a financial catastrophe (*)
{that is why I bought used-like-new, both the Q-7 and the K-30 six months later}
As I indicated earlier, if s/he needs to save, then there isn't necessarily any reason to buy anything.
There is no reason to expect a "Q" system to fail any time soon, and recent upgrades to most systems have been largely subtle.
(*) We had moved from Massachusetts to Indiana; our house in Massachusetts was "under water" figuratively when we moved, because we our mortgage was something like $20K more than the assessed market value when we moved {remember the "housing bubble" in the US}. That next winter, the house had not yet sold, and the realtor forgot to check the thermostat - lots of people had been through the house, according to him, so there had been lots of opportunity for someone to "monkey with" the thermostat. Then he got a call that someone had gone past the house and had seen water pouring out the windows. It turned out that a water pipe had frozen-then-broken in the upstairs bathroom, and slightly warmer weather had started water flowing again, and now parts of the house were literally under water. We had a friend in town who was a contractor; he hired people to do the job of completely stripping the first floor {he took no pay for his work; most of the physical labor was done by high school students, including his daughter; she also refused payment} so professionals could dry it out and avoid mold. When no one lives in a house, you have to get "vacant property" insurance. The insurance which the realtor had recommended to us protected Bank of America better than it protected us - damage resulting from "water from a pipe" was not covered. Mercifully, I don't remember the exact figures now, but we spent something like $30K to have the house dried out and we eventually sold the house for something like $50K less than the original assessed market value.
